Michael Siegel, a tobacco researcher at Boston University, has been quoted as saying that e cigarettes should carry far fewer chemical risks than regular tobacco cigarettes. And although tobacco contains about 5,000 known chemicals, with a potential of another 100,000 additional chemical components as of yet unidentified, he also said that e cigarettes eliminate many of those known and unknown ingredients.
Sixteen studies were analyzed by Siegel and colleagues, all discussing the contents of e cigarettes. Their report in the Journal of Public Health Policy stated that levels of certain harmful chemicals were equivalent to levels found in nicotine patches, and hundreds of times lower than levels found in tobacco cigarettes. And in addition to their findings regarding chemical composition of e cigarettes the researchers also found evidence that use of e cigarettes appears to reduce smokers’ cravings; not only cravings for nicotine, but also for the tactile satisfaction, a need to hold something in their hands, and the oral satisfaction, a need to put something in their mouths.
Siegel and his team identified very important benefits associated with the use of e cigarettes, and published their findings in a reputable public health journal. It is easy to see that e cigarettes offer much greater potential for user satisfaction than nicotine patches or nicotine gum, and yet those two nicotine delivery methods are approved by the FDA as smoking cessation devices and e cigarettes do not enjoy the same status.
